Take note: unlike the level-0 version, you will still be making / tests -- this means that you can only commit // icons to the tests. With the effect of Mind over Matter (0), on the other hand, you turn those into tests (and so can only commit / icons).

I just want to highlight our good friend Luke, who has the following things going for him to make this work: 1) A secret box that brings him to places connected to every open location about three times a scenario, and 2) a pretty much uncontested accessory slot. So yeah, this card is about better than average with him.

An interesting pick for a blessed/cursed Carolyn Fern. Letting her take damage/horror when she has none to heal and helping her to heal when she does. Also I can see Father Mateo+Paradoxical Covenant being insane, basically adding 2 bless and 2 curse tokens every 2 rounds (taking damage then healing it).

Calvin Wright will love this card. +1 to each of his skills and Bless tokens in the Chaos bag as a fast action.

Other survivors running Peter Sylvestre and/or Jessica Hyde won't mind this either.

Of course, being 2XP, Agnes Baker can also make use of this as the horror will trigger her ability, while the curse tokens can be used to power up Armageddon & Eye of Chaos if you then use this to heal her.

Preston Fairmont, with False Covenant in play, will like this. So will Minh Thi Phan with Blasphemous Covenant.

Father Mateo can also make use of it, thanks to the Blessed keyword. Allowing him to more reliably make better use of cards like Radiant Smite and Blessing of Isis.

Edit:

As has been pointed out, I missed a couple. ;)

Tommy Muldoon, thanks to his interaction with defeated assets (and ability to recycle them), can synergise this card nicely with the likes of Brother Xavier and Tetsuo Mori. Allowing him to fill the bag with bless tokens whilst building to those cards being defeated. Thus triggering their abilities and earning Tommy a load of resources into the bargain.

Carolyn Fern, on the other hand, gains an asset that can be used to place horror that can be healed later, though some painkillers might be needed to deal with the collateral damage (and create more horror to heal later).

I'm not sure how this card made it through playtesting, but Mandy in particular would love this card. Since there is no limit to how many times it can be activated (and you don't even need to use any secrets), she can easily fish out her weakness along with all the research cards in her deck before moving on past the player window to finish the skill test. If it was a particularly difficult/important test (or if she felt like it), she could even fish out all Three Aces at the cost of 3 of the secrets.

I anticipate errata for this card coming very soon.

Note: I say easily, but it'll be very time consuming at only 3 cards at a time. The rest of the players will not be happy as they wait for the performing investigator to go through all the necessary searches until they are satisfied they've found everything that needs to be found in their deck.
